Abstract :
A new concept to miniaturise optical trapping and manipulation systems is presented. Integrated optical traps based on top-emitting vertical-cavity surface-emitting lasers (VCSELs) with near-infrared emission in combination with photoresist microlenses were fabricated, characterised and demonstrated. Elevation and trapping of 10 μm-sized polystyrene particles in water is achieved at optical output powers as small as 9 mW.
